'abnormally-situated' originates from the combination of 'abnormal' and 'situated'. 'Abnormal' comes from Latin 'abnormis', where 'ab-' meant 'away from' and 'norma' meant 'rule'. 'Situated' comes from Latin 'situatus', the past participle of 'situare', meaning 'to place'.

'abnormis' transformed into the French word 'anormal', and eventually became the modern English word 'abnormal'. 'Situatus' transformed into the English word 'situated'.

Initially, 'abnormal' meant 'away from the norm', and 'situated' meant 'placed'. Together, they describe something placed away from its usual position.
